There 1S2. pipe 5 for each of the Cincinnati, in the county of Hamilton and two or more fuel chambers as may be in the (so 5 State of Ohio, have invented certain new furnace, the said pipes are connected to a and useful Improvements in Smoke-Conpipe 6 on the outside of the furnace by suming Furnaces, of which the following isv couplings 7. The pipe 6 extends across the a specification. front of the furnace above the doors 2 and is This invention relates to smokeless comj connected to a vertical steam pipe 8, on. the 1o bustion furnaces, and pertain especially to outside of the furnace. The pipe 8 is supimprovements in smoke consuming furnaces. plied with steam through a valve coupling The object of the invention is to provide 9, hereinafter particularly described, by a novel and peculiar means for introducing pipe 10, from the boiler 11, of the furnace. jets of steam and air combined into the fire The coupling 9 contains a valve 12 se- 15 box and over the fuel simultaneously with cured to a valve stem 13, working in a the opening of the furnace door for stoking cavity li of the coupling 9, and through a whereby a more complete oxidation of the packing gland 15 of the coupling 9. The fuel and the prevention of smoke is atvalve 12 is slightly larger than the diamtained. eter of the coupling 9, so as to make its seat 20 A. further object of the invention is to in said coupling to close communication provide novel and peculiar means connected between the pipes 8 and 10. A shaft or ro with a steam valve and operated by opening 16 is adjustably connected at one end to the the furnace door or doors for injecting steam valve stem 13, preferably by a key 16 and to the fire box simultaneously with the openl a setscrew 17, and said shaft is journaled 25 ing of such doors, such means adapted to in hangers 18 on the front of the furnace automatically close the door and simultanebelow the doors 2; to this shaft 16 is secured ously cut ofi such injection. by suitable bolts 2 a pair of triangular Other special objects, advantages and imbrackets 19 one in front of each door 2 of proved results are attainable through an the furnace. lhe brackets 19 are so fixed 30 by the construction and arrangementof the to the shaft 16 as to permit the doors 2 to several parts, as will be hereinafter fully strike the inclined arm of the brackets as disclosed. the doorsare opened and thereby turn the In the accompanying drawings forming shaft 16 to open the valve 9 simultaneously part of this application: Figure 1 is a front with the opening of the doors, so that steam view of a portion of a furnace showing the may be admitted to the fuel chamber only application of the invention.
